Application filed May 3, 1910. Serial No. 559,176.

' To all whom it may concern:

ing cross lines or wires that is mounted on the removable member; the removable member carrying one of the means of adjustment for the cross lines, and the body member of the instrument carrying the means of adj ustment for the other member; by which arrangement the porro prisms can be removed for cleansing and replaced in the precise former position and the cross lines or wires, upon reassemblage of the members being in the precise same position of adjustment.

In the accompanying drawing representing an embodiment of my invention, Figure 1 is a vertical section through the instrument. Fig. 2 is a broken section on the line 22 indicated in Fig. 1. Fig. 3 is a bottom plan view of the removable member. Fig. 4 is a section on the line 4-4 indicated in Fig. 1. Figs. 5, 6 and 7 show different views of the slidable support. Fig. 8 is one end view of the removable holder, and Fig. 9 is a View of the opposite end. Fig. 10 is a horizontal section on the line 10-10 of Fig. 1. Figs. 11, 12 and 13 show different views of the slide that carries the cross lines or wires; and Fig. 14 is a plan of the holder member.

The device is shown as comprising a body member 20, having an eye piece member 21, and an objective member 22, the arrangement of which forms no part of the present invention. The body member has its top portion open or removed for the reception of a holder member comprising essentially a cap or top portion 23, from which depend two supporting walls 24 and 25. The said walls support the reflecting elements, preferably porro prisms 26 and 27 respectively secured thereto in any desired manner, which are usually arranged with their longitudinal axes perpendicular, to cause the usual gages its channel 29.

double refraction at each member, to take the rays from the objective 22 and direct them into the eye piece 23; which latter two members are arranged out of alinement'.

On the wall 24 is mounted a guide member 28, having a dove-tailed portion 19 sliding in a dove-tailed recess 29 in a support 30, that is shown separately in Figs. 5-7. The support has a screw-threaded bore 31 in which operates a screw threaded rod 32, that projects through the top of the holder member and carries a dial 33, and an operating head 34, whereby the screw can be turned to bring various indicating marks on the dial to register with a given mark adjacent thereto on the cap of the holder. The endwise movement of the screw rod is prevented by disk 35 thereon engaged by the socket portion 18 of the cap. on one side and by an overhanging ring plate 36 011 the other.

The support 30 has another dove-tailed slot or channel 40, in which reciprocates a slide member 41, shown separately in Figs. 1l13, the bevel edges 42 and 43 of the slide engaging the side walls of this channel. It will be observed that the path of this slide is at right angles to the path of movement of the support on the guide member 28, that en= This slide member carries the cross lines of the instrument, and these may be of any desired construction, either actually filament members such as wires, threads, or spider web; or they may be lines etched on a transparent member such as glass. In this application the term cross-lines is used to comprehend any desired arrangement that will produce the effect of minute filaments. The vertical line '0 is parallel with the path of movement of the holder member in its guide; while the horizontal line it is parallel with the path of movement of the slide. Consequently, the shifting of the support by the said screw adjustment will bodily move the horizontal line it in a vertical path; while the movement of the slide on the holder will bodily shift the vertical line 0, in a horizontal direction.

The means for shifting the slide on the support, independent of any movement of the support, in the present invention is shown as comprising a screw member 50 turning in a threaded bore 51 in the body member, and provided with a head 52 and a dial 53. The extremity of this screw membei will engage an abutment wall or extension 44 on the slide member 41, and serve to advance the slide in one direction. Resilient means carried by the support are provided, to engage the slide member and advance it in the other direction; in other words to retain it in engagement with the extremity of the screw 50. A box member 5st is mounted on the support member 30 and carries a coil spring 55, that resses against the abutment 44 on the opposite side from that engaged by the screw, as clearly shown in Fig. 10.

It will be observed that the screw member 50 merely engages the abutment wall, but has no direct connection therewith. Therefore the holder member carrying the slide and the support therefor can be withdrawn from the body of the instrument without disconnecting the parts. The abutment member will merely slide off the end of the screw as the slide is moved out of the instru ment upon withdrawing the holder. For returning the same, one edge of the abutment is preferably beveled as shown at 56 in Fig. 12, to engage the screw and compress the spring. Since the spring presses the abutment of the slide against the end of the adjusting screw, when the holder is removed and IQZISSQHlblCCl, this spring will cause the slide to be returned to its precise former position. And the other screw adjustment being carried by the removable holder entirely, no alteration whatever is made in its adjustment upon removal and reinsertion of the holder.

Having thus described my invention, I claim:
